My 6.0 does just fine for me.
Yep,it's a great engine as well as the Ford 6.2 gas..Matched with these new transmissions they perform great with a TC on..I used my son's 6.0 HD 2500 all the time..Pulled a 30ft 8500# TT all over these hills around here..It did great..
I never have understood this posting hp/tq of a pickup like it was a '56 chevy/327 and still in high school..LOL..It's a pickup and any of these engines will work just great with any of the TC's out there..Start towing 8K+ trailers with the TC and then your getting into diesel power..I have hauled truck campers with everything from the Ford straight 6 to the 283/327/350/390/454 and the 460..They all did fantastic with a truck camper and even towing two horses back to the trail head hunting..
I have a new TC in my future or new to me but not a new pickup so I'm stuck with the old 7.5 Ford and the anemic 410 ft pounds of torque..LOL
